Have you done the User Account Control (UAC) dance yet? Oh, it’s great fun, especially when you first start to use Vista. Basically, every time you try to make an administrator type of change or even a change to your Internet Explorer homepage, you are prompted for proper credentials. To turn off UAC, go to Control Panel, and simply enter UAC into Search. Under User Accounts, you will see the link to “Turn User Account Control (UAC) on or off”. There is a box to check whether you want it on or off.
I know that I personally did not have the luxury of one complete Vista Business edition rollout to my company. Vista slowly worked its way into the mix, so to speak. I soon learned that Group Policies do not play nice with Vista, in a Windows 2000/2003 Server and XP environment, so disabling UAC for most users, despite its noble intentions, was a wise choice.
This works for work or home on most versions.
